Abstract
Dot map is one of quantitative cartographic presentation methods used for geovisualization. Traditionally, it was a task of a qualified cartographer to distribute dots in the map. Nowadays, when maps are prepared not only by specialists, it is necessary to develop methods for automatic map production, which will be accessible for a wide range of GIS users. The author presented a new approach to automation of dot maps production. In the study, a building object class from Database of Topographic Objects BDOT10k was combined with statistical data on population and average useful floor area of dwelling in given administrative units. Size and value of dots were calculated with use of hexagonal tessellation. The author also introduced an algorithm for hexagons clusterization with use of dot value. Examples of maps prepared with use of the described method were prepared for a couple of districts of Małopolskie Province.
